Y
Y/C. - A video format found in Super-VHS video recorders. Luminance is marked with Y and is
produced separate to the C, which stands for chrominance. Thus, an S-VHS output Y/C requires
two coaxial cables for a perfect output.
Y, R-Y, B-Y. - The general set of component video signals used in the PAL system as well as for
some encoder and most decoder applications in NTSC systems; Y is the luminance signal, R-Y is
the first color difference signal and B-Y is the second color difference signal.
Y, U, V. - Luminance and color difference components for PAL systems; Y, B-Y, R-Y with new
names; the derivation from RGB is identical.
